General Safety Instructions
2.2.2.2 Checking the Fuel/Air Ratio Control System
Save setting values (curve parameters) for actuator elements, fuel and combustion air through
the complete range of burner firing rate in sufficient number.
Select setting values of fuel and combustion air considering combustion chamber pressure,
fuel pressure, temperature and pressure of the combustion air in order to guarantee proper
operation with adequate excess air through the entire range of burner firing rate.
The burner/boiler manufacturer has to document this by measuring reference values of the
combustion process.
2.2.2.3 Checking Burner Sequencer Part
Check the following:
•
Correct setting of time parameters (especially safety and pre-purge periods).
•
Whether an ionisation or approved self-checking flame sensor is used as only these types
allow continuous operation.
•
Functioning of flame sensor
–
in case of flame blow-off during operation
–
parasitic light being present during pre-purge period
–
missing flame formation at the end of the safety-period
•
Check the performance of all available and/or essential incoming signals, such as:
–
Air pressure switch
–
Gas pressure - min./oil pressure - min.
–
Safety interlock chain (e.g. STB)
•
Activated leakage control function for gas valves if required for application purposes.
–
If necessary, ensure a correct leakage quantification.
